Ok, now you really are making me sound like a career counselor

(which mind you isn't so far off from the formal job that i do)
I mean if you're sure that you are interested enough in theology/philosophy to pursue them as long time interests, you should really think about doing a masters in that field, and try and get a scholarship to do a Phd in that field. If you're interested enough, i'm sure you'd enjoy researching and teaching the subject as a full time job.
Plus a career in academia offers more job security, less working hours, more personal and professional fulfillment(though that depends on the person's personality and what he considers personally and profesionally fulfilling), you'd also avoid the more dynamic, cut throat, high stress, long working hours of corporate life.
